wav of the' "tab 15. The bottom edges 13 The invention relates to a paper cup intended generally for individual use only and composed of a suitable grade of paper ofl the required stiffness and thickness to retain the contents the desired length of time. It has for its object an open-mouthed, rounded cup of this character and composed of a single piece of the paper material, which cup shall have a smooth interior with the usualsubstantially circular mouth piece of the tumbler type of cup but the sharp edge bottom of the closed mouth and flat envelope type, combining the advantages of both.

The invention has for a further object a cup which may be conveniently stacked, as by nesting a plurality of cups; and which shall be of such shape, moreover, that dispensing of individual cupsmay readily be eii'ected as by a suitable cup dispensing machine, in manner well understood. A still further object of the invention consists in the provision of a cup which will allow of forcing out of the contents, such as fruit ices, etc., thru squeezing the body of the cup or by rolling up the same from the bottom, the remaining portion of the cup meanwhile retaining generally its form.

The nature of the invention, however, will best be understood when described in con'- nection with the accompanying drawings, in which i Fig. 1 is a perspective view of the novel IFig. 2 is a front elevation, and Fig. 3 is a side elevation thereof.

Fig. 4 is a plan view.

Fig. 5 is a .plan of the blank from which the cup is formed up.

Referring to the drawings, Fig 5 thereof illustrates 'the blank from which the cup is to be formed, and consists of a sector having the upper arc 1() and radial sides 11 and 12. The bottom ofV the sector is partly cut away; by the edges 13 and 14, which may be arcs arranged substantially at right angles to the respective radial sides 11 and 12, and by an intermediate tab 15; extending outwardly from the bottom of the blank with its axis substantially coinciding with the medial radius of the sector.

In forming the cup from this blank, the sides 11 and 12 are caused to overlap, as indicated in Figs. 1 and- 2, and to be secured to each other b a suitable adhesive in manner such that t e union is substantially midand the blank at the bottom is bounded f and 14 will thus be in juxtaposition and the seam therebetween is sealed by turniiier over slightly the said edges, as along the dotted lines a, b, c, d, to aford the usual ,safety fold and bending upwardly the said tab 15 which is also then secured by a suitable adhesive to the cup body and over the lower portion of the sealed sides thereof. Various forms of tabs may be employed, of course, and I do not wish to be restricted to the particular shape of tab shown; also, when not required, the safety fold may be omitted and merely the tab employed Jfor the sealing. rl`he cup is completed by spinning or rolling over its upper edge 10`to provide a bead 16 or rolled-over rim which not only insures against a sharp edge, when the cup is presented to the lips in use, but serves more especially to maintain the rounded distended form of the cup body with the mouth piece substantially circular, as shown, the body being more or less conical in tapering both ways toward the flattened bottom. This cup, moreover, is of a shape best suited for convenient and natural holding by the hand while providing ample rigidity, and it does not have the tendency to slide out/of ones hand as is the case with a purely conical cup. Furthermore, the beading 16 provides fora rim ofv suicient rigidity to allow of assistance in the forcible introduction into the cup of materials such as ice cream, fruit ices and the like. The rim is` also of suiicient rigidity to enable the cup to resist co1- lapse under the weight of the contents and will maintain under all conditions likelyv to be met with the circular or elliptical shape of the mouth piece and the generally rounded form of the body, notwithstanding the sharp bottom termination of the base. The cup', also, is of considerable depth and for the amount of material .employed in its construction is of relatively large capacity. The construction, moreover, obviates against any dropping out of the bottom as in the case of a two-piece cup and eliminates the iuting required in the construction of a one-piece tumbler type of cup.
